#dusk $DUSK Recently, I helped a friend working on RWA map out a compliant custody path. After going around several mainstream public chains, I found an issue: most chains treat putting assets on-chain as a “registration equals completion” process. But in the real financial world, the boundary of a custodian’s responsibilities is far more complex. Asset management institutions both need to anchor underlying assets to the chain, yet they also can’t expose customers’ position details in a public ledger for anyone to browse. In traditional custody, this dilemma is covered by layers of legal agreements. Once moved on-chain, the usual levers disappear.
$DUSK’s approach here is indeed quite different. Instead of trying to model the custody relationship with generic smart contracts, it separates proof of ownership and access rights already at the token standard layer. Using zero-knowledge proofs, the custodian can externally prove that the asset exists and has not been misappropriated, while the details are only accessible to compliant audit parties that hold the decryption keys. In essence, this design carries the “confidentiality + auditability” dual requirements from traditional custody into the protocol layer—not by patching it in the application layer.
That said, I’ve always felt that completeness of the technical architecture is only the first step. What truly slows institutions from moving on-chain isn’t chain performance, but the trust deficit among legal teams regarding the idea that “on-chain title verification is equivalent to legal title verification.”
Another easily overlooked point is the fracture in the liability chain of custody. In traditional finance, the liability chain between the custodian bank, sub-custodians, and the central depository is very clear—if something goes wrong, you can trace it to the specific party and step. But once on-chain custody introduces multi-party key splitting and conditional decryption, determining responsibility after an incident becomes extremely ambiguous: is it a protocol vulnerability, malicious activity by nodes, or key leakage? The evidentiary burden is an order of magnitude higher than in the traditional system.
So I do recognize DUSK’s long-term direction. In this niche of compliant custody, it has indeed nailed the real needs. But at this stage, I’m more inclined to treat it as an observation position—wait for the first batch of licensed custodians to truly run the full business workflow and obtain legal opinions, then we can make a judgment without hurry. Do you think on-chain custody will ultimately replace traditional custodian banks, or only function as a parallel auxiliary system? @Dusk
